CAR-DIAPHRAGM.

Application led 'January 11, 1917. Serial No. 141,748.

To all whom t may concern.'

Be it known that I, EDWARD E. Vinrr- Morin, a citizen oli the United States, residing at Chicago, in thc county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Dia.- phragms, of which the following is a speciication. s

The invention has for its special object the provision of an improved metallic diaphragm for railway cars especially adapted for eiiicient and economical application to baggage and postal cars.

Among other consti-notional differences characterizing cars of this type, is the disposition oif the end I-beams of the car which flank the end door way, exterior of the car, the same not being finished in but having their fianges exposed.

In the application of telescopic metallic diaphragme to railway cars as now pra-cticed, considerable expense is involved in providing :tor the attachment of the side members to the car end, pockets or other housings being formed in the car end for the reception ot' the telescoping member adjacent the car, or a special diaphragm side wall member being riveted or otherwise secured to the I-beams or door posts.

According to the present invention, advantage is taken of the characteristic postal for construction, to utilize the I-beams of the car irame'as the inner diaphragm side wall members, the outer liange o1" the beams serving to form the interlocking element for cooperation. with a similar iiange formed on the outer side Wall member carried by the 'face plate. This greatly cheapens the cost of production, reduces the weight by approximately one-half, and facilitates the application of metallic vestibule diaphragme to both new and old cars oi' this type.

In order that the invention may be readily understood by those skilled in the art, a preferred embodiment of the same is set forth in the accompanying drawing and in the following detailed description based thereon. As the invention may be embodied in other and varied constructional ormsthe drawing and description are to he taken in a-n illustrative and not in an unnecessarily limiting sense. In the drawingff Figure 1 is an end elevation of a postal car equipped `with the invention;

Fig. 2 is a fragmentary longitudinal section taken on the line 2-2 of Fig. '1;A

Fig. 3 is a fragmentary horizontal section taken on the line 3 3 oi Fig. 1; and

Fig. 4C is a similar section taken on the line 4:-4 ot' Fig. y1.

As illustrated, the car end lis indicated at 11, the upper end sheathing at 12, the platform at 13, the door posts at 14C and the I- beams o1 the frame at l5. rl`his is the usual construction in cars of the mail or baggage type.

The face plate 16 is carried by the buiier beam and controlled by spring pressed buffer stems as is usual, the same not being herein illustrated; the upper portion of the face plate being resiliently controlled by means of the spring 17 bearing in its medial portion against the face plate and at its tivo ends against the I-beams 15.

A metallic diaphragm supplemental' t0 and arranged for attachment to a car of` this type comprises a box-like structure having the side Wall members 18-18 and cover member 19, preferably Yof apexshape, rigidly connected to and `forming 1n effect an integral structure with the side Walls 18. The side walls `and cover are at their outer edges flanged as indicated at 18'il and 19a respectively, for `attachment to the face plate as indicated. The inner edges of the side Wall members and cover member are outwardly iianged as indicated at 18b and 191 respectively, the former i'or engagement with the fiangcs .151 ofthe I-beams 15 and the latter to serve-as a baille plate to obstruct the entrance of the elements between the said flange 19 and the end finish sheathing 12 of the car. I-bealns 15 may be `out off from the interior ot the car by finish plates 20 and 21, the latte arranged above the flange 19 of the cover diaphragm, x'non'lber.

It will readily be seen that according to the present invention it is a very easy and comparatively inexpensive proceeding to attach to a mail or baggage car the necessary elements for eqlilipping the same' Witha Inetallic telescoping diaphragm, the attachment consisting in substance oi. a box or inverted U conu'n'isingthe side wall members 'l'and cover member 19, the inner fiangeslofthe same inter-locked with the outer flange ofl 'the I-beams' and the outer flanges secured to The space between the the existent face plate of the vestibule. The

f weight is much less than that of metallic y sense of being externally visible, and yet may be exposed in the sense of being available for coperation, in the manner hereinbefore indicated, with the side wall members of the diaphragm, thus enabling the utilization of the I beams as elements of the diaphragm constructioni wherefore the claims are to be thus liberally construed except as otherwise specifically limited in terms.

I claim:
